Canadian jazz musician who achieved crossover success with her sultry, unforced contralto voice and her piano playing.

As a child Krall played classical piano, sang in a church choir, and learned to play and sing the Fats Waller songs in her father's record collection. She began playing piano professionally at age 15 and later studied at the Berklee College of Music in Boston and privately with jazz pianist Jimmy Rowles. Performing in the United States and Canada, she developed a repertoire that included subtle, sophisticated songs and spare accompaniment—a cool jazz rhythm section featuring her own piano, occasionally augmented by discreet string-orchestra backgrounds.

Krall's first album, Stepping Out, was released in 1993, and her breakthrough came three years later with All for You, a tribute to Nat King Cole that spent more than a year on the jazz best-seller lists. She gained a wider audience with When I Look in Your Eyes (1999), for which she also received her first Grammy Award. Later albums include The Look of Love (2001) and the concert recording Live in Paris (2002). On The Girl in the Other Room (2004) Krall for the first time included some of her own compositions as well as songs written or cowritten by British singer-songwriter Elvis Costello (Costello, Elvis), whom she had married in 2003.
